1G-Rank (global)

Global ranks are assigned by a consensus of the network of Conservation Data Centres (CDCs), scientific experts, and the Nature Conservancy to designate a rarity rank based on the range-wide status of a species, subspecies, or variety.

(Global Status from MNR Biodiversity Explorer May 2011)

G1 Extremely rare - usually 5 or fewer occurrences in the overall range or very few remaining individuals; or because of some factor(s) making it especially vulnerable to extinction.

G2 Very rare - usually between 5 and 20 occurrences in the overall range or with many individuals in fewer occurrences; or because of some factor(s) making it vulnerable to extinction.

G3 Rare to uncommon - usually between 20 and 100 occurrences; may have fewer occurrences, but with a large number of individuals in some populations; may be susceptible to large-scale disturbances.

G4 Common - usually more than 100 occurrences; usually not susceptible to immediate threats.

G5 Very common - demonstrably secure under present conditions.

2S-Ranks (provincial)

Provincial (or Subnational) ranks are used by the Natural Heritage Information Centre (NHIC) to set protection priorities for rare species and natural communities. These ranks are not legal designations. Provincial ranks are assigned in a manner similar to that described for global ranks, but consider only those factors within the political boundaries of Ontario.

(Provinical Status from MNR Biodiversity Explorer May 2011)

S1 Critically Imperiled - Critically imperiled in the nation or state/province because of extreme rarity (often 5 or fewer occurrences) or because of some factor(s) such as very steep declines making it especially vulnerable to extirpation from the state/province.

S2 Imperiled - Imperiled in the nation or state/province because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation from the nation or state/province.

S3 Vulnerable - Vulnerable in the nation or state/province due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation.

S4 Apparently Secure - Uncommon but not rare; some cause for long-term concern due to declines or other factors.

S5 Secure - Common, widespread, and abundant in the nation or state/province.

S#S# Range Rank - A numeric range rank (e.g., S2S3) is used to indicate any range of uncertainty about the status of the species or community. Ranges cannot skip more than one rank (e.g., SU is used rather than S1S4).

SX Presumed Extirpated - Species or community is believed to be extirpated from the nation or state/province. Not located despite intensive searches of historical sites and other appropriate habitat, and virtually no likelihood that it will be rediscovered.

SH Possibly Extirpated (Historical) - Species or community occurred historically in the nation or state/province, and there is some possibility that it may be rediscovered. Its presence may not have been verified in the past 20-40 years. A species or community could become NH or SH without such a 20-40 year delay if the only known occurrences in a nation or state/province were destroyed or if it had been extensively and unsuccessfully looked for. The NH or SH rank is reserved for species or communities for

which some effort has been made to relocate occurrences, rather than simply using this status for all elements not known from verified extant occurrences.

SNR Unranked - Nation or state/province conservation status not yet assessed.

SU Unrankable - Currently unrankable due to lack of information or due to substantially conflicting information about status or trends.

SNA Not Applicable - A conservation status rank is not applicable because the species is not a suitable target for conservation activities.

3COSEWIC (Committee on the Status of Endangered Wildlife in Canada)

(federal status from COSEWIC May 2011)

EXT Extinct - A species that no longer exists.

EXP Extirpated - A species no longer existing in the wild in Canada, but occurring elsewhere.

END Endangered - A species facing imminent extirpation or extinction.

THR Threatened - A species likely to become endangered if limiting factors are not reversed.

SC Special Concern (formerly vulnerable) - A species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threats.

NAR Not At Risk - A species that has been evaluated and found to be not at risk of extinction given the current circumstances.

DD Data Deficient (formerly Indeterminate) - Available information is insufficient to resolve a species' eligibility for assessment or to permit an assessment of the species' risk of extinction.

4OMNR (Ontario Ministry of Natural Resources)

(provincial status from MNR June 8 2011)

The provincial review process is implemented by the MNR's Committee on the Status of Species at Risk in Ontario (COSSARO).

EXT Extinct - A species that no longer exists anywhere.

EXP Extirpated - A species that no longer exists in the wild in Ontario but still occurs elsewhere.

END Endangered - A species facing imminent extinction or extirpation in Ontario which is a candidate for regulation under Ontario's Endangered Species Act (ESA) (END-R designations are no longer relevant as species are covered under new ESA April 2009)

THR Threatened - A species that is at risk of becoming endangered in Ontario if limiting factors are not reversed.

SC Special Concern (formerly Vulnerable) - A species with characteristics that make it sensitive to human activities or natural events.

NAR Not at Risk - A species that has been evaluated and found to be not at risk.

DD Data Deficient (formerly Indeterminate) - A species for which there is insufficient information for a provincial status recommendation.

7 MNR Significant Wildlife Habitat Technical Guide Area Sensitive Species

Area Sensitivity is defined as species requiring large areas of suitable habitat in order to sustain population numbers

From: Ministry of Natural Resources. 2000. Significant Wildlife Habitat Technical Guide. Fish and Wildlife Branch, Wildlife Section. Science Development and Transfer Branch, Southcentral Science Section. 151pp. + appendices.

8 Habitat Use

I=interior species, I/E=interior edge species, E=edge species (Freemark and Collins, 1989); M/F=Marsh/Fen, S/B=Treed Swamp/Bog. Interior bird species require habitat which is often found 100m from the forest edge while Interior/Edge species are found within both interior and edge habitat. Often Interior and Interior/Edge are more sensitive to urban encroachment as they require these large, relatively undisturbed forest habitats to support viable populations. The increasing urbanization of rural areas often results in increased parasitism and predation as well as disturbance from human recreational activities (e.g. illegal bike trails, dumping and pets.) (Freemark, K. and Collins, B. 1989. Landscape ecology of birds breeding in temperate forest fragments. – In: Hagan III, J. M. and Johnston, D. W. (eds), Ecology and conservation of neotropical migrant landbirds. Smithsonian Inst. Press, pp. 443–454)

Preferred Habitat Habitat Presence within Study Area Observed During Field Surveys

Vegetation

Northern Hawthorn (Crataegus dissona) A S3 R3

Sandy open upland forests as well as richer forested banks, stream borders, forested hills, river bluffs; roadsides, fencerows, fields, meadows, pastures8.

Potential to occur within hedgerows and woodlands, along roadsides and in old fields and meadows.

No observations.

Schreber’s Wood Aster (Eurybia schreberi) A S2S3 R1 Damp to mesic deciduous (maple, elm, oak),

mixed woods thickets, shaded roadbanks12

Potentially suitable / marginal habitat occurs in cultural thickets and hedgerows throughout the study area.

No observations.

Woodland Flax (Linum virginianum) A S2 R2 Dry, open woods and fields10.

Potential to occur within cultural meadow and cultural woodland areas throughout the study area.

No observations.

Virginia Lungwort (Mertensia virginica) A S3 R2

Moist deciduous woods and thickets, usually on floodplains. Sometimes cultivated and some populations may have originated as garden escapes10

Limited potential to occur in Unit N28 – Willow lowland deciduous forest, associated with West Morrison Creek upstream of Dundas Street.

No observations.

Avifauna

Barn Swallow G

Barn Swallows often live in close association with humans, building their cup-shaped mud nests almost exclusively on human-made structures such as open barns, under bridges and in culverts. The species is attracted to open structures that include ledges where they can build their nests, which are often re-used from year to year. They prefer unpainted, rough-cut wood, since the mud does not adhere as well to smooth surfaces13.

Potential to occur in culverts and on human-made structures throughout the study area. No observations.

Bobolink (Dolichonyx oryzivorus) D S4B THR THR

Prefer tallgrass prairie and other open meadows but also use hayfields, and build small nests on the ground in dense grasses5.

Confirmed habitat exists in the greater Dundas Street study area (Brant Street to Oak Park Boulevard) – one Bobolink observation by Ecoplans, in a cultural meadow area approximately 400m east of Neyagawa Boulevard, on the north side of Dundas Street, approximately 25m north of the right-of-way. Potentially suitable habitat occurs in the agricultural and cultural meadow areas along the project limits, depending on how the fields are managed year-to-year (i.e., hayfields, grassland and lightly grazed pasture are ideal, whereas row crops are not).

Yes, Ecoplans’ observed one bird ~ 25m north of Dundas Street, ~ 400m east of Neyagawa Boulevard.

Eastern Meadowlark (Sturnella magna) F S4B THR THR

Prefer grassland habitats, including native prairies and savannahs, as well as non-native pastures, hayfields, weedy meadows, herbaceous fencerows, young orchards, golf courses, grassy roadsides, young oak plantations, grain fields and grassy airfields with elevated singing perches. The minimum area required is estimated at 5 ha3.

Confirmed habitat exists in the vicinity of the greater Dundas Street study area (Brant Street to Oak Park Boulevard) – MNR indicated recent observations (2012). Potentially suitable habitat occurs in the agricultural and cultural meadow areas along the project limits as.

No observations by Ecoplans. (MNR correspondence 2012) Location of observation unknown but not expected in immediate vicinity of Dundas Street.

This bat generally is associated with old-growth forests composed of trees 100 years old or older. It relies on intact interior forest habitat, with low edge-to-interior ratios. Relevant late-successional forest features include a high percentage of old trees, uneven forest structure (resulting in multilayered vertical structure), single and multiple tree-fall gaps, standing snags, and woody debris.11

These bats prefer partly open country with large trees and woodland edges. They avoid deep woods and open fields. Summer roosts probably are mainly in tree foliage (including attached lichen clumps) and occasionally in buildings; caves may be used as night roosts between foraging forays. Hibernation sites usually are in caves or mines with high humidity. Generally, maternity colonies utilize manmade structures or tree cavities; often these are in open sites that would not be tolerated by most other bats (Schmidly 1991).11

No suitable habitat within this study area. N/a

Herpetofauna

Milksnake (Lampropeltis triangulum) A S3 SC SC SC 1 C

Farmlands, meadows, hardwood or aspen stands; pine forest with brushy or woody cover; river bottoms or bog woods; hides under logs, stones, or boards or in outbuildings; often uses communal nest sites2

Potential habitat present within the study area and vicinity generally, and possibly around residential properties (e.g. composters, old sheds, debris piles).

No observations

Jefferson X Blue-spotted Salamander, Jefferson genome dominates (Ambystoma hybrid pop. 1)

A S2 END END THR 1 U

Woodland vernal pools, typically in mature and semi-mature deciduous-dominated forests. Pools are critical as breeding habitat; adjacent upland forest areas are used as summering and wintering habitat.

No suitable habitat in study area, however potential habitat identified beyond limits of study by LGL (2009) in the Bronte Creek corridor.

N/a

Aquatic

Redside Dace (Clinostomus elongates) A S3 END END SC 3

Slow moving sections of small streams (1-10m wide) with overhanging vegetation and pool-riffle habitat. Watercourse sections flowing through open habitats with overhanging vegetation, undercut banks and submerged branches are most suitable.

Recovery habitat identified by MNR in 14-Mile Creek East downstream of Dundas Street to the west of these project limits. There is very little suitable habitat within this study area.

N/a

Silver Shiner (Notropis photogenis) E S2S3 THR SC SC 3

Found in large streams with widths generally greater than 20 m, where it is found in deep riffles or pools adjacent to riffles with moderate to high gradients. This species is rarely in small streams or rivers. Silver Shiner appears to avoid areas with heavy vegetation and siltation.

No habitat in this study area. Habitat present in Bronte Creek and 16-Mile Creek, to which Shannon’s Creek, Munn’s Creek and West Morrison Creek ultimately outfall.

N/a

Bloater (Coregonus hoyi) A S4 NAR NAR

This species occurs in large lakes, usually at depths of about 30-190 meters (Page and Burr 2011). Larvae in Lake Michigan often are near the bottom at about 100 meters (Scott and Crossman 1973). Spawning occurs over all sorts of bottoms usually at about 50-100 meters (Becker 1983).11

Suitable habitat includes clear, deep waters of lakes (38-121 m), usually between 55 and 91 m, with water temperatures between 1.5-11.4°C (preferred range 4-7°C). There is no suitable habitat for this species anywhere within the study area.

5SARA (Species at Risk Act) Status and Schedule The Act establishes Schedule 1, as the official list of wildlife species at risk. It classifies those species as being either Extirpated, Endangered, Threatened, or a Special Concern. Once listed, the measures to protect and recover a listed wildlife species are implemented. EXT Extinct - A wildlife species that no longer exists. EXP Extirpated - A wildlife species that no longer exists in the wild in Canada, but exists elsewhere in the wild. END Endangered - A wildlife species that is facing imminent extirpation or extinction. THR Threatened - A wildlife species that is likely to become endangered if nothing is done to reverse the factors leading to its extirpation or extinction. SC Special Concern - A wildlife species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threats. Schedule 1: is the official list of species that are classified as extirpated, endangered, threatened, and of special concern. Schedule 2: species listed in Schedule 2 are species that had been designated as endangered or threatened, and have yet to be re-assessed by COSEWIC using revised criteria. Once these species have been re-assessed, they may be considered for inclusion in Schedule 1. Schedule 3: species listed in Schedule 3 are species that had been designated as special concern, and have yet to be re-assessed by COSEWIC using revised criteria. Once these species have been re-assessed, they may be considered for inclusion in Schedule 1.

The Act establishes Schedule 1 as the official list of wildlife species at risk. However, please note that while Schedule 1 lists species that are extirpated, endangered, threatened and of special concern, the prohibitions do not apply to species of special concern. Species that were designated at risk by COSEWIC prior to October 1999 (Schedule 2 & 3) must be reassessed using revised criteria before they can be considered for addition to Schedule 1 of SARA. After they have been assessed, the Governor in Council may on the recommendation of the Minister, decide on whether or not they should be added to the List of Wildlife Species at Risk.
